Adjustment of the gain for the photo sensors. * Type-B: Modification of the BS yaw damping control. * Type-Bp: * Type-C: == Other items == * Oplev: * ACC: * Commissioning: * Vacuum system: Replacement of the CC-10 in the Y-arm. * Heater control: * TMS: == Post O4a == * Measurements of the DAC noise: PRM on 8/4. Type-B/Bp was finished. * Measurements on the sensor correction in SR2: 1 night. * Optimization of the damping control in PRs: Measurements 2 days, Test 3 days. * IP control with the ACCs: Long-term test in IY. * In-vacuum accelerometer for IOO: Outgassing from the pod should be checked. * Hight adjustments of Type-A in the cooling: [[https://paper.dropbox.com/doc/Hight-adjustment-in-cooling--B7ii3omB81JIm6khnBt_7fcaAQ-swWQ5h6M6lSs8yLp5D6dA|The procedure]]. * Temperature control for the Oplev: Implementation of the heater controller. From IY in the next week. == Discussion == ---------- = VIS Meeting = Date: 2023/8/4 10:30-11:20 Participants: Takahashi, Akutsu, Mitsuhashi, Tanaka, Shibai == Summary Report == === Type-A === * Height adjustment in IX, IY, and EY. === Type-B === === Type-Bp === === Type-C === * Damping of the OMC suspension. * Prototype test of the blade damper. * Design of the flexible pendulum damper. === Electronics === === Control === === R&D === * TAMA-SAS experiment * Preparation for the IP controls. == Schedule == * Monitoring and offload of Type-A during the cooling. * TAMA-SAS experiment. == Toward O5 == * [[https://paper.dropbox.com/doc/VIS-upgrade-toward-O5--B6qw57_1ZTHOEO_ZdAZi0hBjAQ-PJElGnRfe5jbNPeHWDHzi|Dropbox paper]] == Discussion == == Next meeting == * 2023/8/18 10:00-
